Linear and whorled nevoid hypermelanosis (LWNH) is a rare skin condition characterized by swirls and whorls of hyperpigmented macules in a reticulate pattern along Blaschko's lines; approximately 40 cases have been reported in the English language literature. We report a case of LWNH occurring in a 20-year-old man with widespread involvement over the trunk, face, upper limbs, and genitalia in association with scoliosis. A small hyperpigmented area on the abdomen was treated with a medium-depth chemical peel regimen using 70 percent glycolic acid and 35 percent trichloroacetic acid with no benefit. This is the first report of LWNH treated with medium-depth chemical peel.
